Recognised government bodies such as Standards Australia, US Department of Transportation (DOT), National Highway Traffic Safety Administration (NHSA) and the Food and Drug Administration (FDA) require that a product meet certain specifications and conformance methodologies in order to be registered or certified.

To confidently select a breathalyser, it is important to be aware of these certifications as they ensure the quality and consistency of a breathalyser, and the delivery of accurate BAC readings.

For better performance and longer product life, the breathalyser should be recalibrated as required and the devices’ sensor should be replaced according to manufacturer guidelines.

There are three types of alcohol sensor technologies to measure BAC:

1. Semiconductor Sensor  Standard Models - AL2500 & AlcoSense Elite

The breathalysers with the most value for money, with accuracy in BAC readings to +/- 0.01.  An ideal gift or promotional item.

2. Semiconductor Sensor Professional Model - AL6000Pro

A Standards Australia approved device to test deep-lung air samples with sensor replacement required every 400-500 uses. The AL6000Pro can be used for BAC measurement by drivers, schools, medical industry professionals or as a personal device.

3. Fuel Cell Sensor - AlcoSense Precision Breathalyser

The best sensor available on the market, with accuracy in BAC readings to three decimal places. No sensor replacement required, and calibration is recommended every 12 months. The breathalysers with the fuel cell sensor are designed for hundreds of uses daily, and are utilised by police, as well as medical, transport, aviation and mining industries.

1. Waiting 20 minutes after drinking before blowing into the device.
2. Always using a mouthpiece.
3. Using only ALKALINE BATTERIES.
4. Replacing batteries when the "battery low" signal appears.
5. For AL6000Pro: blowing gently until the beep stops.
6. Never sharing your beathalyser with other people.
7. When not in use, keeping the device in its pouch and removing batteries.
8. Keeping the device away from the moisture or water.

Most people find it difficult to gauge their own blood alcohol level as there a number of factors that need to be taken into consideration. A person’s BAC levels are influenced by body weight, the type and quantity of alcohol consumed, the amount of time over which alcohol is consumed, fitness levels, general health, and amount of food eaten in that time.

Current government laws relating to driving and alcohol consumption vary for different licence holders:

• Learner (L-platers) and Provisional Licence (P-platers): 0.00% BAC
• Professionals Drivers of heavy trucks, buses, trains and trams: 0.00% BAC
• Open Licence Holder: below 0.05% BAC

Men: No more than two standard drinks in the first hour and one standard drink each hour after.

Women: No more than one standard drink each hour.

PLEASE NOTE: It takes the liver about one hour to process one standard drink of alcohol. There is a possibility after a heavy night's drinking that a person's BAC level will still be over 0.05% the following morning. BAC cannot be reduced by having coffee, cold showers, vomiting or exercise. There are heavy penalties for drink driving and they include fines, disqualification for a period of time and imprisonment.

However most importantly do not risk your life or someone else's. Do not drink and drive!
